WINDOW LATCH".

Application filed July 28,

The invention is a latch.' for windows or the like which will positively hold the windowl in any position and which may readily be operated.

Theobject of t-he invention is to provide a. device for positively holding windows similar to car windows which may readily be gripped by hand to operate it.

Another object of the invention is to provide a device for holding window sash in any position which is of a simple and at the same time durable construction.

And a further object of the invention is to provide a device which may be placed on the corners of window sash so that a lslidable holt therein will engage a means for holding the saine in the frame.

lith these ends in view the invention embodies a window latch having a spring bolt slidably mounted in a casing, a lever for positively operating the bolt, a means for preventing the bolt sliding inward without raising the lever, a means for securing the bolt in the inner or outer position, and a rack for engaging the outer end of the bolt which may be placed in the window frame.

Other features and advantages of the invention will be seen from the following description taken in connection with the drawings, wherein Figure 1 is a view showing the device as it would be installed in the corner of the window.

Figure 2 is a rear view of the device.

Figure 3 is an end view of the device looking toward the bolt end.

In the drawings I have shown my device as it would be constructed wherein numeral 1 indicates the casing, numeral 2 the bolt, and numeral 3 the operating lever.

The casing 1 may, be constructed as shown with a U-shaped central portion 4 having flanges 5 and 6 at the ends. The bolt 2 which is of rectangular shape is slidably mounted in the slot 7 in the section 4 and its rear end is provided with a round section 8 that projects through an opening 9 in a webA 10 at the rear end of the section 4. The end of the section 8 is provided with a beveled surface 11 as indicated by a dotted line in Figure 27 and this surface engages a similar surface 12 on a projection 13 of the lever 3 when it is endeavored to force the bolt 2 inward without raising the lever 3. A spring 14 is placed around the sec- 1924. Serial No. 728,573.

tionV 8 to force the bolt outward. to the position-shown in Figure 2. 'lhe central por,-

tion of the bolt l2is provided with a .slotv which extend-s from the dotted line 15 to a dotted line i6 and the end 17 `of the lever 8 projects .into the slot and bears against the surface at the line 16 to-force thebolt inward when the lever is raised. This portion of the bolt is also provided with notches 1S and 19 into which a key 20 may be snapped to hold the bolt in the inner or outer position.

The lever 3 which may he constructed as lshown is provided with an out-standing knob 21 and pivotally mounted on a pin 22 between the flange 5 and an ear 23 of the casing 1. The end 17 of the lever 3 is bent as shown in Figure 2 so that it will extend downward into the slot in the bolt to operate the bolt rlhe lower end of the projection 13 of the lever 3 is provided with a smaller projection 24 which will engage the under side of the section 8 of the bolt and prevent the lever being raised while the bolt is forced backward against it.

The key which is provided with a knob 25 at its outer end may be moved upward and downward in a slot 26 in the casing and may he held in either position by a spring 27 engaging a notch 28 in its side or bearing downward on its upper edge.

The casing 1 may be attached tol the lower edge of a window as shown in Figure 1 and held by screws 28 at the corners, and the holt may engage teeth 29 in a bar 30 that may be inserted in the side of the window frame. The bar 3() may be provided with a notch 31 which may engage the upper side of the bolt when the sash is in the lower position as shown in Figure 1 to latch the sash in this position.

lt will be understood that changes may be made in the construction without departing from the spirit of the invention. One of which changes may be in the general design of the casing, bolt or lever; another may be in the design of the bar another may be in the omission of the latch 20; and still another may be in the use of any other suitable means for returning the bolt to the outward position in place of the spring 1 4.

The construction will be readily understood from the foregoing description. To use the device it may be installed in the lower outer corners or corner of a window sash or the like and it will be seen that normally l it will latch the window as shown in Figure l. To raise. the window Vit will only be necessary to pull upward on the knob 2l and it will be scent-hat as the knob raises l5 the end 17 of the lever 3 will move backward and draw the bolt 2 inward until its outer end is out of engagement with the teeth 29 of the bar 30 soV that it will be possible to raise the sash, and after the bolt is past l? the notch 3l it will only be necessary to push upward on the sash yand the bolt will .snap backward and forward as it passes over the teeth 29. lt will also be seen that once the window is raised it will be absolutely ini l5 possible -for it to move downwardly without raising the knob 2l as the outer end of the bolt will form a positive seat on the teeth 29.

Having thus fully described the invention, what I elaiin as new and desire to secure by Letters Patent, is

ln a window latch, a bolt having a slot in its central portion slidable in a casing, a lever with one end projecting into the slot of the said bolt, a knob at the opposite end, and a proj ection below the knob with a notch 25 in it to engage the rear end of the said bolt, said lever being adaptable to draw the said bolt inward, resilient means i'or forcing the said bolt outward, said bolt being provided with notches in its upper side, and a key for 30 engaging the said notches to secure the said bolt in either the inner or outer position.
